However Published research into their water quality improvement performance has, been sporadic and often contradictory. In order to address this situation, a cooperative study was initiated in 2009 by Wollongong City Council and the University of Wollongong to investigate the pollutant reduction performance of an existing water quality control pond. The pond was monitored for a period between 2009 and 2010 and a unique method for estimating constructed wetland performance was developed to address limitations found in other studies. This method incorporated automated sampling, high temporal resolution monitoring and standard least squares procedures to fit multivariate statistical models to estimate the pollutant reduction performance. The monitoring results were used to calibrate and validate a model which is able to quantitatively assess uncertainty. Results from this study suggest the method applied could be used as a standard method for estimating the pollutant reduction performance of other similar water quality improvement systems.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"359 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124517736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Palla. Plants were collected from three different sites were grown in non-aerated hydroponic conditions. Four levels of NaCl, 0, 100, 200 and 300 mM, were maintained in solution culture to investigate the response of growth and photosynthesis to salt stress. Schoenoplectus triqueter showed optimal growth at 100 mM NaCl and better photosynthetic response to salt stress than that recorded in the other two species (S. lacustris and S. juncoides). Net CO2 assimilation rate (A) of S. juncoides remained unaffected up to 200 mM NaCl, but thereafter at 300 mM NaCl it decreased drastically. In contrast, in S. triqueter, CO2 assimilation was found to be stimulated at 100 and 200 mM NaCl, whereas such stimulation in net CO2 assimilation in S. lacustris was found only at 100 mM NaCl. Transpiration rate decreased in S. lacustris and S. triqueter with increasing salt stress, whereas in S. juncoides it increased at all salt levels. Stomatal conductance decreased in all three species at 300 mM in. Water use efficiency (WUE=A/E) in S. triqueter increased with increase in external salt concentration of the three Schoenoplectus species. Schoenoplectus triqueter was more efficient in controlling stomatal movement. The dominant anatomical traits related to S. triqueter (the most tolerant among all species) were found to be stomatal size, shape, and density, high water use efficiency, low transpiration rate, and low reduction in photosynthetic rate and chlorophyll pigments. Moreover, stomata were oriented in distinct grooves.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129673832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, very little is known about burrowing crab species living in temperate Australian saltmarsh. In the present study four different survey techniques were employed to investigate the diversity and abundance of crabs in the saltmarsh and mangrove at Towra Point. The four techniques yielded different results for species abundance and diversity. Four different species Heloecius cordiformis, Sesarma erthrodactyla, Helograpsus haswellianus and Paragrapsus laevis were found in saltmarsh. Three of these species H. Cordiformis, S. Erthrodactyla and P. Laevis were also found in the mangrove. A higher diversity of crabs were found in the Sarcocornia and Sporobolus saltmarsh communities than those dominated by Jancus kraussii. Pit traps were an effective means of capturing crabs though under-represented H. Cordiformis, and S. Erthrodactyla but was ineffective at identifying crabs in the more heavily vegetated Sporobolus and Juncus communities. Surveying crabs underneath artificial blocks may have over-represented the density of S. Erythrodactyla. Burrow counting is a quick and effective means of estimating crab density, though gives no information on assemblage diversity. The results of the study recommended a combination of pit-trap and visual census as a means of efficiently sampling crab assemblages.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116933202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scott","doi":"10.31646/WA.222","DOIUrl":"https://doi.org/10.31646/WA.222","url":null,"abstract":"Fish kills are highly visible events and media publicity of them is powerful in developing the perception that our rivers are highly degraded through the impact of pesticides or other human insults. Ecotoxicology data derived from laboratory experiments suggests that fish, compared with other aquatic species, are relatively sensitive to pesticides used extensively in cotton cultivation. For example, the organochlorine endosulfan yielded 96-hrLC50s ranging from about 0.1µg/L for European carp to 0.2-2.4µg/L for native species. However, there is anecdotal evidence that fish and other aquatic life are healthy in cotton tailwaters likely to be contaminated. We review database of fish kills in northern NSW and southern Queensland kept by state governments, and report of fish kill frequencies in different river basins, their presumed or suspected causes, the species involved, and whether and which, pesticides were detected in each incident. These databases showed that fish kills were reported more often from cotton-growing areas and during cotton-growing season. More than half the 98 recorded fish kills were associated with pesticides by the investigators. However, many of the records gave only circumstantial evidence as to their cause, and only a few were actually investigated in detail. This makes it difficult to make a proper assessment of how pesticides may be implicated in fish kills or of the impact, more generally, that cotton pesticides are having on fish populations. We also present data on residues of endosulfan found in live fish near a lagoon near Wee Waa before and shortly after a fish kill. We conclude that simply measuring tissue concentrations of pesticide residues does not provide direct proof that a fish died from any pesticides detected. Overall we suggest that more careful scientific attention needs to be paid to and fish kills occurring in irrigation areas before we can know the real extent of damage from pesticides and therefore what management is needed","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125179828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eighteen sites, consisting of seagrass communities (mainly Zostera capricorni) and bare mud and sand substrata, were sampled by seine net at least once a week during both day and night over a three month period. Of the 985 fish caught, the most abundant species were sand mullet (Myxus eloes an ngates), tamar river goby (Afurcagobius tamarensis), yellowfin bream (Acanthopagrus australis) and mosquito fish (Gambusia holbrooki). Species diversity was found to increase after lagoon opening. Many more of the 27 species caught were foind in the more saline habitats (25sp.) than in the more brackish upland habitats (13sp.). more species were caught during the day (24sp.) than at night (16sp.). catches of juvenile (20-50mm) Myxus elongates increased significantly after lagoon opening. Catches of Afurcagobius tamarensis and Acanthopagrus australis also increased after lagoon opening but this was probably due to high turbidity and changes in estuary morphology rather than salinity. The sizes of the fishes caught suggest that the lagoon acts as a nursery area, although some adult fish were also found.","PeriodicalId":197128,"journal":{"name":"Wetlands Australia Journal","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128572118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
